Field Detail

UNSCOPED

public static final Scoping UNSCOPED

No scoping annotation has been applied. Note that this is different from in(Scopes.NO_SCOPE), where the 'NO_SCOPE' has been explicitly applied.

public static final Scoping SINGLETON_ANNOTATION

SINGLETON_INSTANCE

public static final Scoping SINGLETON_INSTANCE

EAGER_SINGLETON

public static final Scoping EAGER_SINGLETON

Method Detail

forAnnotation

public static Scoping forAnnotation(java.lang.Class<? extends java.lang.annotation.Annotation> scopingAnnotation)

forInstance

public static Scoping forInstance(Scope scope)

isExplicitlyScoped

public boolean isExplicitlyScoped()

Returns true if this scope was explicitly applied. If no scope was explicitly applied then the scoping annotation will be used.

isNoScope

public boolean isNoScope()

Returns true if this is the default scope. In this case a new instance will be provided for each injection.

isEagerSingleton

public boolean isEagerSingleton(Stage stage)

Returns true if this scope is a singleton that should be loaded eagerly in stage.

getScopeInstance

public Scope getScopeInstance()

Returns the scope instance, or null if that isn't known for this instance.

getScopeAnnotation

public java.lang.Class<? extends java.lang.annotation.Annotation> getScopeAnnotation()

Returns the scope annotation, or null if that isn't known for this instance.

acceptVisitor

public abstract <V> V acceptVisitor(BindingScopingVisitor<V> visitor)

applyTo

public abstract void applyTo(ScopedBindingBuilder scopedBindingBuilder)
